This DSP has been seen to make bright flashes in the past. At a range of only 1000 miles or so, it could make very bright flashes. I looked for this DSP about 02:38 UT last night and for your unid about 03:25 last night. I did not see anything. Because the inclination was wrong on my unid elset and the height is quite low, my predictions were off more than 10 degrees. And I was trying to observe from the city, not BCRC. Since the time discrepancy is so large, I assume that this object maneuvered into a slightly higher orbit some months ago. If so, then my best guess based on your observations 6 days apart is: DSP F19 USA 142 1 25669U 99017A 08183.11274676 0.00000000 00000-0 00000-0 0 01 2 25669 28.5239 166.6687 7137557 107.8287 336.4576 2.32785000 08 Our next chance will be Sunday evening.
